If most of the measurements in a large data set are of approximately the same magnitude except for a few measurements that are quite a bit larger, how would the mean and median of the data set compare and what shape would a histogram of the data set have? (a) The mean would be smaller than the median and the histogram would be skewed with a long left tail. 4 (b) The mean would be larger than the median and the histogram would be skewed with a long right tail. (c) The mean would be larger than the median and the histogram would be skewed with a long left tail. (d) The mean would be smaller than the median and the histogram would be skewed with a long right tail. (e) The mean would be equal to the median and the histogram would be symmetrical.

Afactory makes propeller drive shafts for ships. a quality assurance engineer at the factory needs to estimate the true mean length of the shafts. she randomly selects four drive shafts made at the factory, measures their lengths, and finds their sample mean to be 1000 mm. the lengths are known to follow a normal distribution whose standard deviation is 2 mm. calculate a 95% confidence interval for the true mean length of the shafts. input your answers for the margin of error, lower bound, and upper bound.
